Abstract

To select a channel adapted to detection of the position of a liver. The position "m" of the border between the liver and the lung is obtained from a profile. A sum Sliver of signal intensities in a liver region R1 and a sum Slung of signal intensities in a lung region R2 are calculated. After obtaining the sums Sliver and Slung of the signal intensities, Sliver and Slung are compared to determine whether Sliver is equal to or less than Slung. In the case where Sliver is equal to or less than Slung (Sliver≤ Slung), a channel is not selected as a channel used at the time of detecting the position of the edge of the liver. On the other hand, in the case where Sliver is larger than Slung (Sliver > Slung), a channel is selected as a channel used at the time of detecting the position of the edge of the liver.

Abstract

[Problem] To reduce the burden on an operator who operates an endoscope. [Solution] A projecting means (81) moves vectors (N, U, V) in parallel in a manner such that an origin point (O1) of a coordinate system (CH) is positioned on the line of extension of the vector (N) defined by the endoscope (30). After moving the vectors (N, U, V) in parallel, the projecting means (81) projects coordinate axes (AP, RL, SI) onto an endoscopic image. Then, the projected coordinate axes (AP, RL, SI) are displayed with the endoscopic image on a display unit (10). As a result, it is possible for the operator to verify information about the coordinate axes (AP, RL, SI) by looking at the endoscopic image displayed on the display unit (10).
